AWS Step Functions - How to Express Task Parameters in serverless.yml

Serverless Framework
,

Hi,

I have a step function that has a number of tasks where I define parameters. For example:

"MyLambdaTask": {
  "Type": "Task",
  "Resource": "arn:aws:lambda:xxx:xxx:function:MyLambda",
  "Parameters": {
    "feed.$": "$.feed",
    "bucket.$": "$.mediaPath.bucket",
    "key.$": "$.mediaPath.key"
  },
  "ResultPath": "$.mediaPath.info",
  "Next": "RegisterAsset"
}

How do I translate the Parameters section into the serverless yaml format?

Thanks,
